Description
The CBX 5 Star Rating & Review plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'page' parameter in all versions up to, and including, 1.0.7 due to insufficient input sanitization and output escaping.

Compliance Impact

The vulnerability allows unauthenticated attackers to perform reflected cross-site scripting (XSS) attacks by injecting arbitrary web scripts that execute when an administrator interacts with a crafted link.

Such XSS vulnerabilities can lead to unauthorized access to sensitive information or session hijacking, which may impact the confidentiality and integrity of data.

Consequently, this could affect compliance with standards like GDPR and HIPAA that require protection of personal and sensitive data against unauthorized access or disclosure.

Executive Summary

The CBX 5 Star Rating & Review plugin for WordPress has a vulnerability known as Reflected Cross-Site Scripting (XSS) in the 'page' parameter. This occurs because the plugin does not properly sanitize or escape input and output data. As a result, an attacker who is not authenticated can inject malicious web scripts into pages. These scripts execute if an administrator is tricked into clicking a crafted link.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary scripts in the context of an administrator's browser session. This can lead to theft of sensitive information, session hijacking, or unauthorized actions performed with administrator privileges. Since the attack requires tricking an administrator into clicking a link, it relies on social engineering but can compromise the security and integrity of the affected WordPress site.
